View Full Version : 360 GTC whitebody prep

I recently purchased a 360 GTC whitebody and would like to do as much body grinding/sanding as possible before painting.

With the side clips in the standard position and the chassis not lowered at all, the body seems to be positioned really nicely. When depressing the rear of the car the motor mount hits the chassis before the body hits the ground. The rear wheel wells also look pretty good with the +1 rear wheels.

The front of the body seems more likely to bottom out though. I am thinking I should grind that a little bit, but I am also trying to decide if I should just grind the front lip off entirely before starting. Does anyone think this lip helps handling; or is it just aesthetic? Should I just grind it off before painting?

So..

Should I get rid of the front lip?
Should I glue the body clips in the standard position?

don't get rid of the entire front lip, but trim it back so it is flush with where the top of the body is, this will prevent it from getting caught under the rails of the RCP Track. if you take to much of the front lip off it will weaken the front of the body.

I wouldn't change the mounting points of the clips. it sit in a pretty good location. the front is pretty low anyways.

other that that is a really good track body without any other modification.

I'm not sure how much this means to remove.. Do you mean flush with the bumper?

^ Thats what Brian is talking about. He just reccomends shaving enough of the spoiler, so that the bumper hits the RCP before the spoiler can. Copying either of the posted pics should get you the results you are shooting for.

Me personally, I shaved the sides of the spoiler down a bit at the corners, but I left mostly the whole thing on. If you stay off the walls, or atleast minimize impacts to it, you should have any trouble with the spoiler getting hung up.

As far as if these things change handling, the answer is yes. Wether they increase grip by downforce, or just plain weight is still in the air, but I guarantee a body with the full front lip will perform different than a body with no lip. Would every driver notice the sublte change, possibly not. Could you adjust the set up to compensate for what ever changes take place, absolutely.

thanks for clearing that up for me. :)

There is not TRUE right or wrong way to do it. My preference is to take off the entire thing and wet sand it as smooth and round as possible so that you can rub the boards and not get sucked in. Again, not saying that I am right, just stating how I do it on the 360, and the lexus bodies that have the very strong gurny flap on the bottom.

The 360 is one of my all time favorites and a great race body. I trimmed the lip back and rounded it off. It still hit the wall first, but didn't catch. I never liked the look of it completely removed, but when its one the track, you don't even notice stuff like that. I did trim a little off the inside as well to get a little more rear wheel clearance and travel.

dxm2; is that picture a before or after shot? It doesn't look like the lip was trimmed much at all...

You can always trim a small amount then check the results on the track then keep trimming till you find what you like. I know you want to trim it once and then paint it but since you dont know how much you want removed this will be the best option.
I trim my 360s like Dave and they give awesome results for me and my son.
I add an inner stiffener to give the body more durability. Atomic sells them in CF but I use polystyrene sheet (.030")

I do what George said, except I usually leave a little (like what you have on the picture) and reinforce it with lexan sheets. The lexan reinforcement works great, I've used lexan reinforcement on my Porsche 962 front end and I've raced it several times, got into several collisions and its still standing strong (also, that LM body is the first one I've used since Kyosho came out with the first two LM bodies) (Note: LM light buckets are glued to the body from the inside)

It sure doesn't........I'll update it with a current photo.

I don't know where my camera is; or I would take a photo.

So I ground down the lip so that it doesn't protrude any further than the bumper. I was pretty careful about this, and it is actually a little bigger than in the two photos above. Not much, but slightly bigger.

I ran it on some RCP for about an hour today, and it never stuck under the rails. I didn't have the time/patience to run it with the full lip so I can't comment on the difference. All I can say is that it worked pretty well; thank you for the advice everyone.

PS: The 360GTC was *much* nimbler than my 94mm Enzo.

Jeremy - Run the 360 and the F430 GT, you will like both. 2 of my favorite and most run bodies.;):)

Finally getting around to uploading a picture of how I shaved the lip on my 360GTC.

I wanted to make sure the lip was as big as possible, but also I wanted to make sure that it did not extend forward past the bumper. I have run the car 4 times and the lip has never gotten caught under the RCP rail.

May I ask if you leave the headlights empty or attach the light sockets when racing? I read somewhere that people drill holes into the rear of the body for greater downforce. Any truth to this?

Welcome to the forums...

Light buckets... Guess depends on rules of the race, that goes for other modifications on the body... As for drilling holes in the back of the body, I figure is done to let the air flowing under the body to escape faster, and not act somewhat like a parachute...

Just glue in the top clear light piece. Not the under bracket. I usually trim out the rear some for weight and let air out.

I just put stickers over the headlight holes. Aerodynamically speaking, the idea was to keep the flow of air around the body. This body was stable and really fun to drive like that.

That body is quite a bit more beat up now.

Thanks guys for your help. I'm new to Mini Z racing (in the AWD class) so this is all new to me. I've raced 1/10 touring car and 1/8 electric buggy before.
